For those who's running E85 in your ride,do you know how high the content level of the E85 you're running.I was reading this article on LS1tech mentioning that E85 can vary between 51-85% content level. I'm going to switch over to E85 on 2002 Camaro SS and i want to straight E85 content level not anything below that.I know Sheetz runs E85 but how high the content level of the E85.

I found the article on LS1tech mentioning E85 can varies between 51-85% content level.

( Lastly, the actual ethanol content in E85 can widely vary in different areas from anywhere between 51-85%. The consequences of running E85 that has a significantly lower ethanol content in a car tuned for 85% ethanol content can have catastrophic results, aka things can go boom! )

I run 93 and E85 in my 2010 CTS-V at @750rwhp. It is true that the actual percentage can vary greatly.

In an accurately tuned ride with a quality E85 sensor, the tune will automatically scale with the E content that you are currently at. I have run full tanks straight 93 when in areas that don't have E85 available. I have also run full tanks of E85 with varying content between 60-83%. I have also run half 93 and half E85 with my Aeroforce gauge showing around 20% E.

All of this without changing anything on the car. The tune manages it all.

I guess my point is that it can be safely done with good parts and an experienced tuner.

*Edit* Don't expect to regularly find E85 from the pump with an actual 85% ethanol content. MAYBE if you buy it by the barrel you could get that.

I can have all the parts to run flex fuel like (Fuel Pump,Inj) and other parts. The main issues is that my ecm from my 2002 Camaro SS is not designed or equip to handle going between regular and corn base fuel. You can only choice one or the other.

Yup, get a blue/green ECM from a newer Tahoe, Silverado, Suburban and you're set. I'll be doing the exact thing on down the road in my chevelle. Have larger injectors and flex fuel sensor sitting on the shelf waiting on me. It's one wire from flex sensor to ECM, power, ground, then you can adjust the tune to the alcohol content.

Look up sloppy mechanics on youtube. Matt spent some time making videos about the flex sensor, he was hooking it up to a microsquirt box, but the sensor still operates the same w/ GM ecm.

Now we need somebody to hit all the Sheetz gas station and other gas station that carry E85 in the area and test the content level of the E85. Their are 21 Sheetz gas station in the area from Wake Forest,Garner,Raleigh,Fuquay-Varina,Wendell,Morrisville,Cary,Apex.

I can help provide some real-world / current updates on that:

The Sheetz at Banks Road off Hwy 401 between Wake Technical College and Fuquay-Varina consistently tests at 86-88% for me.
I've had readings as high as 90% and as low as 84% once.
Been getting E85 for over a year now.

The Sheetz at Hwy. 50 and Hwy. 210 consistently tests at 86-88% for me. It's close to Fastlane and I've been getting E85 for over a year from there.
